In the following description of the embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
1 (a) and 1 (b) are diagrams for explaining a posture correcting apparatus according to an embodiment of the present invention.
FIG. 1 (a) shows the front view of the user, and FIG. 1 (b) shows the back view of the user. 1 (a) and 1 (b), a posture correcting apparatus according to an embodiment of the present invention includes a plurality of motion sensors S1, S2, S3, and S4, an information collecting unit 100, (200) and a plurality of actuators (A1, A2, A3, A4). Depending on the embodiment, at least some of the aforementioned components may be omitted.
Depending on the embodiment, at least some of the components described above may be affixed to a user's body, or to a wearable device (including routine clothing) that the user may wear.
Hereinafter, in describing the embodiments of the present invention, it is assumed that the components of the posture correcting apparatus exist in a form attached to the wearable device.
The plurality of motion sensors S1, S2, S3, and S4 are distributed to the user's body to acquire their three-dimensional coordinate information. Then, the obtained three-dimensional coordinate information is provided to the information collecting unit 100. In one embodiment, the plurality of motion sensors S1, S2, S3, S4 may be disposed on both sides of the user's shoulders and on both sides of the user. The acquisition of the three-dimensional coordinate information may be performed periodically.
The plurality of motion sensors S1, S2, S3, and S4 may transmit the obtained three-dimensional coordinate information to the information collecting unit 100 through the first data path 110. The first data path 110 may be formed of a conductive material. For example, the first data path 110 may be formed of a conductive nano wire.
According to an embodiment, the motion sensors S1, S2, S3, and S4 may transmit the obtained three-dimensional coordinate information to the information collecting unit 100 through human body communication.
In one embodiment, the plurality of motion sensors S1, S2, S3, and S4 may be any one of an acceleration sensor, a gyro sensor, a geomagnetic sensor, and a pressure sensor, . For example, the plurality of motion sensors S1, S2, S3, and S4 may be a combination of a three-axis acceleration sensor and a three-axis gyro sensor.
The information collecting unit 100 transmits the three-dimensional coordinate information collected from the plurality of motion sensors S1, S2, S3 and S4 to the feedback control unit 200 through the third data path 310. [ In one embodiment, the information collecting unit 100 may combine three-dimensional coordinate information collected from a plurality of motion sensors S1, S2, S3, and S4 within a predetermined time interval, and transmit the information to the feedback control unit 200 .
For example, when the distances from the information collecting unit 100 to the respective motion sensors S1, S2, S3, and S4 are different from each other, three-dimensional coordinate information from each of the motion sensors S1, S2, There may be a difference in the time at which the data is received. Therefore, time synchronization is performed on the three-dimensional coordinate information received from each motion sensor S1, S2, S3, and S4 within a predetermined time interval, and time-synchronized three-dimensional coordinate information is transmitted to the information collecting unit 100 Lt; / RTI >
Meanwhile, the third data path 310 may be formed of a material having conductivity as in the first data path 110.
The feedback control unit 200 estimates the user's current posture based on the three-dimensional coordinate information received from the information collecting unit 100. [ Estimation of the user's current posture may be performed based on the three-dimensional coordinate information corresponding to each of the motion sensors S1, S2, S3, and S4, and the distance between the motion sensors S1, S2, S3, May be to calculate the angle between each motion sensor S1, S2, S3, S4.
If the user's current posture is estimated, the feedback control unit 200 compares the estimated current posture with a preset standard posture, and if the estimated current posture does not match the preset standard posture, Control is performed. For feedback control for the user's posture correction, a standard posture needs to be set first, which will be described below with reference to FIG.
For feedback control for the posture correction, the feedback control unit 200 may determine at least one of a region, a direction, and a distance to which the user should move in order for the estimated current position to conform to the standard posture. Then, a feedback control signal is generated based on the determined contents, and the feedback control signal can be transmitted to an actuator positioned at a site where the user should move.
For example, it is assumed that the estimated current posture is shifted to the left side of the shoulder portion as compared with the standard posture. In this case, the shoulder should be moved to the right in order for the estimated posture to match the standard posture. Accordingly, the feedback control unit 200 generates a feedback control signal to be transmitted to the actuators located at the shoulder part of the user and located in the opposite direction to the direction in which the shoulder part should move, and outputs the generated feedback control signal to the corresponding actuators Lt; / RTI >
At this time, the feedback control unit 200 can control at least one of the vibration speed, interval, period, and intensity of the actuator according to the distance that the shoulder part should move in order to match the estimated current posture with the standard posture. For example, a feedback control signal for increasing the vibration intensity or speeding the vibration speed may be generated and transmitted to the corresponding actuators as the distance over which the shoulder part is to be moved is longer.
Meanwhile, the feedback control unit 200 can generate the feedback control signal with reference to the set profile. The profile may define a parameter such that different feedbacks may be provided depending on at least one of a body part where correction is required and a distance d that the body part should move.
For example, as shown in Table 1, different parameters may be defined depending on the body part for which correction is required. For example, the parameters may be defined such that feedback is provided at a higher speed, a faster period, and a greater intensity in the lower shoulder region where the sensitivity is relatively lower than in the side region where the sensitivity is relatively high. Also, for example, different parameters may be defined depending on the distance that the body part requiring correction needs to travel. For example, a parameter can be defined such that the larger the error d, the faster the velocity, the faster the period, and the greater the intensity can be fed back to the site.

Although the information collecting unit 100 and the feedback control unit 200 are shown separately from the information collecting unit 100 and the feedback control unit 200 according to an embodiment of the present invention, It can also be configured in one integrated form.
A plurality of actuators A1, A2, A3, and A4 are distributed to the user's body and perform driving based on a feedback control signal received from the feedback controller 200. [ In one embodiment, the plurality of actuators A1, A2, A3, A4 may be disposed at both sides of the collarbone portion and both scapula regions of the user. In one embodiment, the plurality of actuators A1, A2, A3, A4 may provide at least one of vibration feedback, tactile feedback, and force feedback.
Meanwhile, according to the embodiment, the number of actuators attached to the body part may be different. For example, in a region where a user's sensitivity is relatively low, a large number of actuators can be attached to a region where a user's sensitivity is relatively high.
A plurality of actuators A1, A2, A3, and A4 may receive a feedback control signal from the feedback controller 200 via the second data path 210. The second data path 210 may be formed of a conductive material. For example, the second data path 210 may be formed of a conductive nano wire.
According to an embodiment, the plurality of actuators A1, A2, A3, and A4 may receive a feedback control signal from the feedback controller 200 through human body communication.
As the actuators A1, A2, A3, and A4 are driven, the user takes an action for attitude correction, and a progressive feedback control is performed accordingly.
Although the embodiments using a plurality of motion sensors and a plurality of actuators have been described above, one motion sensor and one actuator may be used according to the embodiment. For example, one motion sensor may be used to sense the user's position biased in one direction. In this case, one actuator may be driven to inform the user that the posture is disturbed. When one motion sensor is used, for example, a nine-axis sensor in which a three-axis acceleration sensor, a three-axis gyro sensor, and a three-axis compass are combined may be used as the motion sensor.
Meanwhile, although not shown in the drawing, the posture correcting apparatus according to an embodiment of the present invention may further include a storage unit for storing a standard posture. The standard posture stored in the storage unit can be used for comparison with the current posture estimated by the feedback control unit 200 and read.
In addition, although not shown in the drawings, the posture correcting apparatus according to an embodiment of the present invention may further include a power supply unit for supplying power to each component. An energy harvesting technique may be applied to the power supply unit. For example, the power supply unit may be formed of a flexible solar cell, or may be an energy conversion module that converts energy generated by a user's physical activity into electric energy.
FIG. 2 is an exemplary diagram for explaining a standard posture setting method according to an embodiment of the present invention.
First, the feedback control unit 200 estimates the initial posture of the user in the initial state. The initial state may be, for example, a case where a specific button provided in the posture correcting apparatus is input, or a wearable device with the posture correcting apparatus is wearing for the first time.
In one embodiment, the feedback control unit 200 can guide the user to take the correct posture for the initial posture estimation. For the guidance, the posture correcting apparatus may include at least one of a display, a speaker, a light emitting diode (LED), and a light emitting type fiber material.
Estimation of the initial posture can be performed based on the three-dimensional coordinate information obtained from the plurality of motion sensors S1, S2, S3, S4 in the initial state. Estimation of the initial posture means that the distance between the respective motion sensors S1, S2, S3, S4 and the angular position of each of the motion sensors S1, S2, S3, S4 on the basis of, for example, And calculating the angle between the motion sensors S1, S2, S3, and S4.
If the initial posture is estimated, the feedback control unit 200 determines the standard posture based on the estimated initial posture. The standard posture can be determined, for example, by applying a threshold range set in the estimated initial posture.
FIG. 2 shows an example in which a standard posture is determined by applying a threshold range th to a user's initial posture as an example. The threshold range th may be greater than or equal to zero. In the following description, it is assumed that the threshold range th is 0 for convenience of explanation. That is, in the following description, it is assumed that the standard posture is the same as the initial posture.
3 (a) and 3 (b) are diagrams for explaining a feedback control method according to an embodiment of the present invention.
3 (a) shows an example in which the user viewed from the above is viewed, and four actuators A1, A2, A3 and A4 are attached to the shoulder part of the user.
If the estimated current position does not match the standard posture, the feedback controller 200 may drive at least one of the actuators A1, A2, A3, and A4 so that the user's current posture conforms to the standard posture.
For example, suppose that the estimated current posture is tilted toward the left direction (D7) with respect to the standard posture. In this case, the feedback control unit 200 determines the direction in which the shoulder part of the user should be moved to the right direction D3. Accordingly, the feedback control unit 200 generates a feedback control signal to be transmitted to the actuators A2 and A4 located in the shoulder region of the user and positioned in the direction D7 opposite to the direction D3 in which the shoulder portion should move And transmit the generated feedback control signal to the actuators A2 and A4.
On the other hand, the feedback control unit 200 can control at least one of the vibration velocity and the vibration intensity of the actuator according to the distance the user has to move. For example, the longer the distance the user can move, the faster the vibration speed of the actuator, or the greater the vibration intensity. To this end, the feedback controller 200 may generate a feedback control signal capable of controlling at least one of the vibration velocity and the vibration intensity of the actuator, and may transmit the generated feedback control signal to the actuators to be driven.
FIG. 3B shows an example of an actuator that is driven to move the user in the direction and a direction in which the user must move in order to match the estimated current position with the standard position.
4 is an exemplary view for explaining a posture correcting method according to an embodiment of the present invention.
In FIG. 4, the predetermined standard posture and the estimated current posture are shown together. S1, S2, S3, and S4 in the standard posture, the coordinates of each of the motion sensors S1, S2, S3, and S4 in the estimated posture are shown as { S2, S3, and S4 are shown as {S'1, S'2, S'3, S'4}.
As described above with reference to FIG. 1, when the current position of the user is estimated, the feedback controller 200 determines whether the estimated current position matches the predetermined standard position. The determination may be made based on, for example, three-dimensional coordinate information corresponding to at least one motion sensor among a plurality of motion sensors S1, S2, S3, and S4.
For example, the determination may be based on three-dimensional coordinate information corresponding to the sensors S3 and S4 located on both sides of the user's side. For example, the feedback control unit 200 calculates the three-dimensional coordinates {S'3, S'4} obtained from the sensors S3 and S4 at the estimated current position and the three-dimensional coordinates { Let the three-dimensional coordinates {S3, S4} coincide. The feedback control unit 200 receives the three-dimensional coordinates {S'1, S'2} obtained from the sensors S1 and S2 at the estimated current position and the three-dimensional coordinates { By comparing the coordinates {S3, S4}, it is determined whether or not the position of the shoulder part of the user in the estimated current position coincides with the position of the shoulder part in the standard posture.
According to the embodiment, the determination as to whether the estimated current posture conforms to the predetermined standard posture may be performed through comparison of absolute coordinates, or may be performed through a method of comparing distances and angles between sensors. When a method of comparing distances and angles between sensors is used, the amount of computation can be reduced as compared with a method of comparing absolute coordinates.
If the determination result does not match, the feedback control unit 200 performs feedback control for the posture correction of the user.
For the feedback control, a process of determining at least one of a part to be moved, a direction and a distance should be performed as described above. In this example, since the portion to be moved is the shoulder portion, only the determination of at least one of the direction and the distance to which the shoulder portion should be moved is required.
Referring to FIG. 4, the shoulder portion of the user in the estimated current posture is biased to the left of the shoulder portion in the standard posture. Therefore, the feedback control unit 200 determines the direction to which the shoulder portion should be moved to the right. Accordingly, the feedback control unit 200 generates a feedback control signal for driving the actuators A2 and A4 located on the opposite sides of the direction in which the shoulder portion should be moved, and transmits the feedback control signal to the actuators A2 and A4 .
At this time, the feedback control unit 200 controls the driving of the actuators A2 and A4 on the basis of the distance d offset by the shoulder portion of the user in the estimated posture compared to the shoulder portion in the standard posture . Since it has been described with reference to Table 1 and FIG. 3, detailed description thereof will be omitted here.
5 is a flowchart illustrating a posture correcting method according to an embodiment of the present invention. Depending on the embodiment, at least one of steps 501 to 509 may be omitted.
In step 501, the posture correcting apparatus estimates the initial posture of the user. For the initial posture estimation, the posture correcting device can guide the user to take the correct posture. Estimation of the initial posture means that the distance between the respective motion sensors S1, S2, S3, S4 and the angular position of each of the motion sensors S1, S2, S3, S4 on the basis of, for example, And calculating the angle between the motion sensors S1, S2, S3, and S4.
In step 503, the posture correcting apparatus determines a standard posture based on the estimated initial posture. The standard posture can be determined, for example, by applying a threshold range set in the estimated initial posture.
In step 505, the posture correcting device estimates the current posture of the user. Estimation of the user's current posture may be performed based on the three-dimensional coordinate information corresponding to each of the motion sensors S1, S2, S3, and S4, and the distance between the motion sensors S1, S2, S3, May be to calculate the angle between each motion sensor S1, S2, S3, S4.
In step 507, the posture correcting apparatus determines whether the estimated current posture conforms to the standard posture. If it is determined that the estimated current posture conforms to the standard posture, the process proceeds to step 505; otherwise, the process proceeds to step 509.
In step 509, the posture correcting device performs feedback control for posture correction of the user. For example, the posture correcting device may transmit a feedback control signal to actuators located in a region where the user is to be moved and located in a direction opposite to a direction in which the user must move.
On the other hand, the profile set in the feedback control for the posture correction of the user can be used. This is as described above with reference to Table 1, so that detailed description thereof will be omitted here.
In the above-described embodiment, the example in which the posture correcting apparatus includes the actuator has been described. According to an embodiment, the actuator may be implemented as another form of feedback providing. For example, the feedback providing unit may be implemented in the form of a speaker or a display. In this case, the feedback control unit may generate a feedback control signal for audio or video output and transmit the feedback control signal to the speaker or display device. Or, for example, the feedback providing part may be implemented with LED or light emitting fiber material. In such a case, the feedback control section may generate an electrical signal for emitting the LED or the light emitting type fiber material and transmit the electrical signal to the LED or the light emitting type fiber material. When the feedback providing part is implemented as a speaker, a display, an LED, or a light emitting fiber material, the provision of feedback through the implementation is recognizable by others. Therefore, a caregiver or a therapist in the vicinity can assist with posture correction.
In addition, the posture correcting apparatus according to embodiments of the present invention may exist in an independent form or in a form attached to a wearable device. According to an embodiment, some components of the attitude correction device may be attached to the wearable device and the remaining components may be separate from the wearable device.
